Is there a way or add-in to automatically add marking lines for a router table?

Sorry if this isn't the right place for this question, but we were wondering if there is a way to automatically create "marking lines" (sorry if there's a better term!), to plates in a part/assembly.  An example of this would be you have a base plate and another plate has to be welded to it at 90° somewhere on that base plate, we would like a marking line put on the base plate so when we send the files off to a router place they can cut the pieces and mark those lines so we can line up the plates on them.

Is there a way to do that in Solidworks or is there an add-in that will do that?

Thanks in advance for any help!
