Constant bar size with tempo map

[Ctd]

Hi all, apologies if his has been covered or if it already exists.

I find the way the main window changes when creating tempo maps irksome.
When you change the tempo in the tempo lane Reaper changes the size of the bars, and the playhead moves at the same speed.
Is there a way to reverse this, where the bar size stays constant and the playhead changes speed?

Cheers

Chris
