Other chain sets #purchasesource to specific value then calls the Add Purchase Information. Can skip the redundant SFE with condition?

One way to do it would be a condition like this on the SFE action(s):

program:
    if globals(_caller) inlist 'my first chain,my second chain, ....' then
        'skip'
    fi

value type > text
comparison operator > !=
Condition value > skip

You can also use a condition to check the value of the said field, presuming the default value in nil.
