How to exclude a register or bit in IMC by certain value

Hi,

I'm using IMC to do the coverage.

I have successfully exclude instance and module, both in ccf file and manually by hand; also I have found the toggle view, which can exclude a certain bit's, rise or fall.

However I was look for the way to exclude by certain value, does anyone know about it?

For example, I have a 3-bit register A. During coverage, I want to exclude it when it was 000, 010, 110, 111. Toggle exclusion seems helpless at this point.
