Hello there Nick,
One possible idea would be to use a global field to hold your wildcard text. And then use script with Set Field step so it would be like this
Set Field your text field ; Let(start = Position(text;global;1;1);Middle(text;start + Length(global) ; Length(text)))
this will save everything in the field past the global contents you enter. you might also want to protect that something is first put into that global field. And you might want to include a possible undo script step in case something goes wrong or put this into a calc field to view the results and then just setting the field with the calc if the results are correct.
