Is it possible to do contains condition on user defined AP hold rule?

Hi - we are attempting to add a condition as a user-defined hold rule that any invoice with a line type of MISC and line description of tariff will be placed on a user-defined hold using this feature rolled out in 24D (linked at bottom). We anticiapte some suppliers may not be case sensitive or include other words/characters as part of their description so would like any line that contains the word tariff to be placed on this hold. I can't figure out how to do that in the spreadsheet given - double clicking or advanced configuration doesn't have option
