Need to store comments from four assessors in list of map

HI guys

I'm chasing my tail here.

We are assessing software against 4 criteria per software title.

For each criterion we have a different assessor group.

The software titles are kept in a list of map since they are not yet approved for our Allow List and we don't want to keep the data if they are not approved.

We have a custom comments record type which has a many-to-one relationship with the software table.

Issue:

For each software title we need to keep 4 comments, but I find I am only able to overwrite the comments value, not append.

Here's the code for my approval details interface:

a!localVariables(
  local!softwareCategoryList: rule!getSoftwareCategoryList(
    includeDisabled: false,
    includedSoftwareCategoryID: if(
      a!isNullOrEmpty(
        ri!mappedValue.software[Global Software.fields.id']
      ),
      null,
      ri!mappedValue.software['recordType!Global Software.fields.softwareCategoryID']
    )
  ),
  a!gridLayout(
    label: "Approve Software",
    labelPosition: "COLLAPSED",
    headerCells: {
      a!gridLayoutHeaderCell(label: "Software Name"),
      a!gridLayoutHeaderCell(label: "Category Name"),
      a!gridLayoutHeaderCell(label: "Vendor Name"),
      a!gridLayoutHeaderCell(
        label: "",
        showWhen: and(not(ri!readOnly), not(ri!edit))
      ),
      a!gridLayoutHeaderCell(
        label: "Comment",
        showWhen: rule!APP_isTrue(ri!mappedValue.decision),
        align: "LEFT"
      ),
      a!gridLayoutHeaderCell(
        label: "Status",
        showWhen: and(ri!readOnly, not(ri!edit))
      )
    },
    columnConfigs: {
      a!gridLayoutColumnConfig(width: "DISTRIBUTE", weight: 3),
      a!gridLayoutColumnConfig(width: "DISTRIBUTE", weight: 3),
      a!gridLayoutColumnConfig(width: "DISTRIBUTE", weight: 3),
      a!gridLayoutColumnConfig(width: "NARROW", weight: null),
      a!gridLayoutColumnConfig(width: "MEDIUM"),
      a!gridLayoutColumnConfig(width: "DISTRIBUTE")
    },
    rows: a!forEach(
      items: ri!mappedValue,
      expression: {
        a!gridRowLayout(
          id: fv!index,
          contents: {

    selectionSaveInto: {},
    allowRowReordering: false,
    validations: {},
    shadeAlternateRows: false,

)

I know there's probably a simple answer but I am drowning in a lake of overthink!

Any help will be gratefully accepted
