You're looking for an option for Strata.

Someone asked this same question 7 months ago and the author said he'd include it in the next update,
which doesn't seem to have happened. I didn't load the add-on to look at how it works but it might be
helpful if you created a test frame and then posted the SavedVariable .lua file contents into some [code]
tags here to see if someone with Lua knowledge can tell you how to add in such a feature. I don't have
the Lua knowledge myself but I have some people I can ask to see if they know how to accomplish this.

I'll be busy with homework and a new video tomorrow (orly? yarly) so I doubt I'll have time to check out the
add-on myself.
