It is, you simply just drag the BPM into a regular automation track, then that automation track will contain the imported BPM, but why would you want to that? -The project will already be fixed in the imported BPM value.
I suspect that what you really do want to do is the control the BPM from a regular automation track, and override the annoying locked imported value(?)
If so First drag the value into your regular automation track, tight-click the BPM-gadget and there choose 'remove-global-automation'. Now it is your regular automation track that controls the BPM, and you are in full control of that.
