Combine stock filters (size and function)

[Buster Charlie]

Sometimes I want to work with a specific part size, but I don't want to show all parts in that sIze. 

 

For example in the stock filters I can show only fuel tanks,  or show parts with a specific resource (say electric charge or monopropellant ), or show command modules,  but I can't only  show size 1 fuel tanks, or surface attach batteries,  or mk3 monopropellant. 

I think a simple change that would greatly enhance my enjoyment of building would be able to select one catagory(reaource, shape, part functuon, manufacter, etc.) Then somehow lock that filter in place before selecting a second catagory, or better  yet also searching.

 

I've tried custom filters, and they are very nice, but sometimes miss mod parts or other hard to categorize parts.

 

I think the stock filters are fine, but it's annoying to search through  all fuel tanks when you know you need a specific form factor.
