Storing link values

Hey folks, 

Is there a way I can store the value of the label in the following link field:

a!linkField(
links: a!startProcessLink(
label: "Manage Service Updates",
processModel: cons!MANAGE_POSTED_FILES_PM,
processParameters: {
pvbStandalone : true(),
orderFiles_bln : true(),
pvnFolderId: cons!FOLDER_SERVICE_UPDATE_NOTICES_ID }
)
)

I need to store "Manage Service Updates" in a ri variable that I can pass to the process model. 

TIA :)
