Definitely not recommended...
I learned this the hard way on a on a project 5 years ago. I had a bunch of TSWs and just used my iPAD project once to test something, setting it to the same IP-ID of one of the TPs...4 hours later, trouble-shooting all sorts of 'Red Herring' rabbit holes, I rebooted everything and got the system back. Discussing this with a Crestron buddy he told me that it was 'expected' behavior!...HaHA!
Having separate devices in your SMW/System also helps tremendously when trouble-shooting, not to mention that each panel is completely independent (though there might be a use-case to have them track each other)...
If you don't already know it, if you Right-Click/Drag from TSW #1 to TSW #2, you'll get a pop-up with a choice to 'Duplicate Device Programming' and even provide the ability to change the headers of all your signals - This is super efficient!
Also, having a standard/formatted header for all your signals (ex: tp001, tp002, etc.) will also facilitate rapid deployment.
then, if you have a logic folder for your first TP, you can just copy/paste the folder and use F9 to search/replace that header to get the next/subsequent TP logic...
Forgive me if this is super basic, but I know that there's many newer guys on this forum, and also, I can't tell you how many times in recent years that this *Old* guy has been shown a tool/method to simplify things that I said "Wow, how did I not know about that!!! - Thank YOU!!!"
HTH!
