Changing tempo while performing live in cue mode

I have set up my cue setup which I want to use for live performance. During the live performance I want to gradually change tempo at moments that are not pre set (so I cannot use the tempomap I suppose).

Is there a way to make these changes? Apart from manually increasing/decreasing tempo in the tempo edit menu 1 or 0,5 bpm at the time?

I use a midi controller that has knobs to change tempo, but not with a midi clock that is running within the midi controller.
