Update 2 tables with a button

Is it possible to update 2 tables with 1 button? I am creating a simple app to track the total number of miles run and biked.
I am using buttons to increment miles by 1 or -1. I want this to update 2 tables, one that has Row Ownership and one that does not.

The one for Row Ownership is so i can populate information on the individual users profile screen.

The one w/o Row Ownership is for a social/friends page so that we can see how each other are doing.

Is that possible?

Yes, use a custom action
