I was a construction electrician and I ran a lot of conduit before I found a job that is a lot less work.  
Anyway, I remember that the NEC allowed a splice in a condulet if it satisfied the fill capacity _and_ had at least three openings, not including the cover, of course.  
Do I remember accurately, and is it still the case? A coworker went a little ape shit when I told him this. He’s not an electrician.  
If he’s right I’ll go ahead and put steak on his black eye. 😉  
Peace,

Are we talking plastic or steel?

Makes a difference in terms of earth bonding.

Here is a link to a discussion of exactly this with NEC cites:

Basically it looks like you are correct. The condulet needs to be marked with it’s volume as well.

ETA: there is also the suggestion to upsize the condulet using reducer bushings to allow more room for the splice.

That’s how we used to do it, with a plug in the unused hub.
