How to consecutively number rows across multiple tables and with different sequential numbers

[Eli Plewka]

I'm writing a procedure. I have steps in tables that are broken up by images, headers, or other various items. I'd love to be able to number these steps 10,20,30,40 and have that numbering persist across multiple tables. Is there anyway that I can do this with built in tools or can this even be done with a user macro?
