Turning 4 fast bars into one slow bar

[Sam.slater.music]

Hello there -
Firstly, not a newbie but grateful for the help offered on here - so thanks for that! I have an issue that's driving me nuts.

There are a number of reasons why this situation has occurred (order of tempo mapping tracks, etc) however, essentially I need to do the following:

Convert bars 107 - 113 into a single bar at the previous tempo (70.4935bpm)
Convert Bar number 113 into (new bar number) 109, and
Have new bar number 109
Not do any damage to the subsequent tempo information.

TLDR; cut out chunk of illogical meter, and replace it with something that the orchestrator can deal with.

I've tried to do this with Cut time / Insert time, based on Samples - strangely enough, it refused to do it accurately.

Any help WELCOMED. Sam
