I’m trying to use an accelerando to go from a tempo marking of 36 to 80, but the accelerando only goes part of the way and then the temp jumps to 80. I know I can draw the line in tempo editor myself, but is there a way to program the accelerando to do so automatically?

You can set the properties of the accel in the lower panel. Unfortunately there is no end bpm value, but set the Final tempo % to 222% and starting from 36 you should end up at 80.

I am brand new to the forum, so please correct me if this is improper use of the thread.
The topic here is related to my problem.
I just imported an XML file into Dorico 4.3.31 from an older Finale file (from 2008, not sure which version of Finale it was created in, but it was opened in Finale 27 and then exported as latest version of XML).
I assigned playback to NotePerformer (4.4) which went amazingly well!
The issue to hand is that a one measure accelerando completely skipped the marked destination tempo. There was another direct tempo change later in the piece, which Dorico read perfectly.
I will attempt to attach the project here.
The direct question is “how to prevent Dorico playback from over-accelerating the accelerando past the target new tempo?”
Thanks so much!

Select the accel. line, go to Properties, and reduce “Final tempo %” so it matches the target.
( 132 to 138 would be 104.54%. )

Thanks so much, Mark! (I didn’t realize there would be maths involved in solving this!)
Is it more or less trial and error? How do I know when I’ve ended up with the right percentage?
As a passing comment, I posted a question to the Finale forums last night. As of this morning no one has even looked at the post, much less answered my query!
I hate to say it, but I have to get out the calculator on my iPhone.
I have long lobbied (on both the Finale forum and here) for the ability to type the target tempo directly, and I hope eventually that will be possible.

It’s as simple as 138 ÷ 132 = 1.04545… Of course you don’t have to match it so exactly. Somewhere close is good enough, because of the flexibility of beats when a human ensemble changes tempo.
Errr, mmm, as mentioned before, I didn’t know there would be maths required!! 
Thanks so much for this, Mark.
