To append a new array for each value within an item

Suppose I have an array with multiple values for key dates:

'type!{urn:com:appian:types}Request'(
'id': "009642",
'status': "Cancelled",

'dates': "05/05/2024, 10/06/2024",
),

'type!{urn:com:appian:types}Request'(
'id': "009641",
'status': "Cancelled",

'dates': "06/15/2024, 02/06/2024, 02/10/2024"
)

I want the result to be such that the dates are individually added and appended having the same data.

so the first array will become


'type!{urn:com:appian:types}Request'(
'id': "009642",
'status': "Cancelled",

'dates': "05/05/2024",
),

'type!{urn:com:appian:types}Request'(
'id': "009642",
'status': "Cancelled",

'dates': "10/06/2024",
),

Like this I want to do for all items in that data. Is it possible in appian?
