A/B or IF/AND/THEN Triggers

We currently have Books connected through Zapier to Ship Station. The current trigger is set so that when an Invoice in Books is marked as PAID, then the Invoice/Order information is sent via Zapier to Ship Station. But we don't to send every single Invoice/Order to Ship Station...since not every Invoice is for an item(s) that needs to ship out.

What we want to see is the following for a trigger option:
IF Invoice is marked as PAID,
AND Invoice custom field PRODUCT TYPE = PHYSICAL PRODUCT,
THEN trigger Zapier to send information to Ship Station.

This is just our situation, I am sure there are many more businesses that have this same need.
