Is there a way to change the BPM Tunebat detects?

When you send the whole song in, it gets the BPM right, but when you send just the acapella, it's wrong 100% of the time.

And i just use Tunebat to speed up or slow down stems, and i always have to send the entire song in to slow it down properly and extract the slowed down song, even when we have official stems for the song, which is quite annoying.

Is there a way that i can change the BPM Tunebat detects before changing my tempo?
