In Constellation, for the OOTB My Work landing page, there is a requirement to enable bulk actions for transferring assignments (not entire case). This is particularly relevant since the case lifecycle includes a stage with parallel assignments. For scenario with parallel assignments, the requirement is to transfer only selected assignments (e.g., 2 out of 3) rather than transferring all assignments associated with the case.
Another article talking about implementation details Constellation Tips: Bulk Transfer Assignment , in the replies it also talks about how to target individual assignments but it still needs to you use the native bulk actions on cases.
I have not seen anyone solve this, so be keen on the communities experience. In my opinion, in order of preference:
Wait for Infinity '26 - there are changes coming that should natively allow this at the assign- level
Case level - Use a list view or insight, with the transfer action to transfer just these type of assignments
Create a “bulk transfer” case - This would be a case that could reference your existing list view then execute the activity on all the assignments.
Create a “bulk transfer” custom DX component - this would need to manage each individual assignment transfer, as there is no POST /assignments/bulk-actions in DX API right now. From what I can see, this is one of the things that '26 will introduce.
