I know that additional parameters has been suggested (over a year ago) and has been voted on. I wanted to add a bit to the idea. As it applies to powerlifting rotation of bars used, and even accommodating resistance (bands/chains) are part of a lot of lifters training.

Allowing additional parameters would help, but what would be more useful would be if the coach to make custom parameters and there they be a check box of whether this category of parameters constituted a separate exercise.

So take Box Squats for Example. Create an exercise called box squat. Then created a Custom Parameter (with separate record checked) for the Bar Used (Squat Bar, Buffalo Bar, SSB, Cambered Bar). Then create a second Custom Parameter for Accommodating Resistance (Bands, Chains ect.)

This would keep coaches from having to created multiple different exercise for every variation.
