Stage Action ZIP Dynamic Parameter

Summary:

Hi,

In OIC integration, I want to assign the dynamic file name for Stage Action (ZIP), something like 'if $filename = AP then assign the filename as "AP_Logs' else 'GL_Logs'

But I do not see any condition check functions

I can create a Switch case before Stage Action and populate the $FileName variable and assign the same in this stage action file name. But I am looking is there any possibility to do the same inside this Stage Action Expression Builder.

Appreciate any inputs!!
