Indirect limits for several moving analog indicators

I am using several moving analog indicators to monitor a cyclic process (9 stages) - so all limits for each moving indicator change 9 times per cycle.

What is the best way to code this into the moving analog indicators? The limits are static for each stage, so I can pre-define them.

Currently, I defined a folder of tags for each stage of the cycle and pick from these as stage changes. But, is there a better way? Can you tell me what you’ve used/would recommend? Thank you.
