Mesh Isolation Tool for mesh with same texture set

I’ve been using Substance 3D Painter for over five years as a texturing artist and truly appreciate its powerful toolset.

However, one recurring challenge is painting hard-to-reach areas such as the inner mouth, armpits, and between the legs, where closely positioned geometry makes it difficult to achieve clean, detailed results.

A feature to isolate or hide parts of the mesh of same texture set—similar to functionality available in software like ZBrush or Maya—would greatly enhance workflow efficiency and precision. I believe this addition would benefit artists across the industry.
