Multiple BPM/Tempos for different tracks in the same file?

I’m doing a cover of Leia. The song starts off slow and gets faster during the chorus. While Eleanor sings fine and matches perfectly with the music during the start at 149 BPM, once it gets to the chorus she gets out of sync, then the other parts that are slower are out of sync.
Did I get the BPM wrong? Or should I make another track with a different BPM? And is that possible?

You can change the BPM and signature at any moment along the song, double click to edit or to create a new marker in in the BPM or signature row; right click to delete.(green lines in the image)



Thank you so much! This is really going to help me out!
