if you have a text column and you do a text filter in it, you can specify the way the text is filtered at start, the only thing they need to do is change the filter value to something else after (see attachment)
But I think the best way to do it is to narrow down the values that are on your Terms table by doing a segregation on the data security for the cube, that way only users that have access to those terms will be able to see them and you can use the "Include All" functionality as normal.
