There may be a desire to increase perspective group limits if they are at the max or nearing the max allowed number of groups. By default, perspectives are limited to 200 groups.
There are a few things you can do to free up space for your perspective:
1. Enable the Auto-Delete feature
2. Merge like named groups (These are typically related assets)
If this still doesn't give you enough room to work with then you can submit a support case for our team to review a manual increase. Be advised that these are typically reviewed by our Engineering team for stability/performance purposes and may take some time to get approved.
