Zapier doesn't accept some kind of Lookup

In the zapier module i can send the Lookup that are directly referring to a specific column over Google sheet, but if I use a Lookup or a Template that refer to a personal user column (then not in the sheet) this won’t be listed in the possible values to pass to zapier.
There’s a solution anyway?

is the relation being looked up from a
multiple relation

I need to check all cases, but certainly in most of the cases yes, from multiple relation.
It is so bad :roll_eyes::grinning:

then you can not use it
you can only use it in single relations

And there is no other way to take out these values, like to put in the spreadsheet or text file or else?
