Edit Properties Action for Multi valued properties

[maheswarim26479]

we have a requirement to add an additional tag to all the pages, while creating the live copy. Is there a way we can handle this using the Edit Properties Action? The examples given in the documentation speaks about single valued property only as below.

sling:resourceType#/(contentpage|homepage)#/mobilecontentpage,
cq:template#/contentpage#/mobilecontentpage

For this use case you can write a custom MSM synchronizing action.

Or else you can add the tags programmatically on creation event of live copy pages.
