Can I add different timing in the tempo track?

There are options to create tempo changes within a song using the tempo track and I can set project to various timings e.g. 1/4 or 4.4. I am wondering if it is possible to use the tempo track to add a tempo change AND a timing change...for example I would like to go from a 4-4 timing at 190bpm to 3-3 timing at 190 bpm and then another change to 4-4 timing at 150bpm.

Is this possible to do with the tempo track or should it be a feature in the next release?
