Is something easier or automatic exist ?

You have more options:

1. Walk All Over You - DOP, OPB and these songs are one-press format.

2. Since you transcribe MIDI files with Reaper, you can trim the MIDI in the sections where the BPM changes; enter the 81 BPM in the Intro section of your BeatBuddy Manager (BBM) and the 162 BPM in a Main Drums Loop section. Note in my link above that the song has several tempo changes throughout.

3. Apply time stretching using your DAW.
