Paint textures and paint details

Hello !
Quite new in Unity 3D and in this forum, I would like to know how is it possible to fetch my Paint textures and paint details: when I click on Edit Textures or Edit Details, a window is opening with a list of all textures I have, but as I have a lot, the list stops at letter G, and I am looking for a texture beginning with M for instance. Is there a maximum number of textures authorized? Is it possible to find the rest of the list? Thanks a lot for your help!

I’m not too sure what you are describing here. Are you viewing textures from the inspector, a material… ?
