Maya Texel Density keeps becoming uniform after I use Layout UVs

Irraka

So I'm trying to layout all my UV's for my model. I have some uv shells that I went to be set at a texel density of 50, others at 75 and a few at 80. I've gone ahead and set specific ones at those levels and clicking get texel density shows that. However after I use UV Layout it's averaging them all at around 81 texel density. How do I preserve the texel density for my shells when using UV Layout?

check the pre-transform options, described here ^

I'm not seeing anything on there for Texel density.

the pre-scaling is what changes the size of your UV shells.
