As with all of my tips, I will say that this may not be the best, or even the only way to do this.

After a few hours, I finally managed to put together a workflow that gave me what I was looking for. So, I used this as a starting point and did some trial and error testing with rules and custom properties. I did find a video that showed the steps needed for these rules, but the forum thread I found it in went on to report that it no longer worked. I take it as a personal challenge, as I did this past week. I don’t like to be told that my software can’t do something I need it to do. There was no easy workflow described, and in fact several of the posts I read said that this is something that can be fairly difficult to achieve. I searched the internet, including the Autodesk Community forum for AutoCAD P&ID.

None of the signal lines, or general instrument symbols contained any of the necessary acquisition rules to make this happen. This turned out to be more of a challenge than I thought it should be. I wanted to create a simple instrument loop where, after placing a primary instrument on a line, all related instruments connected to it took on the same instrument loop number. One that should have been relatively easy.

In my test project, I ran into one particularly challenging operation.

It took a little while just to remember where I had left off, but before long I was making progress again toward getting things set up to our company standards. After one of the craziest summers I have seen since I have been on this job, I finally got a chance last week to get back into setting up my AutoCAD P&ID software.
