Set Multiple SearchField Values In EpiCombo

>> Apply multiple values in EpiCombo searchfilter?

Just wondering if you ever did find a way to do this in a combo?
Anyone know how to set more than one filter in an EpiCombo drop down? In the SearchFilter properties, we can set it to something like CodeTypeID = '<something>' for the User Codes.

I've tried the following, but it doesn't work:

CodeTypeID = 'abc' AND CheckBox01 = true

We're on Epicor 9.05.606.

Thanks,
Nick
