Button customisation

Thanks for pushing on this, DonTino, and for the extra detail on why this matters. A hard brand requirement like "no rounded corners" is a different thing than a styling preference, and that distinction is worth having on record.

You're right that this isn't consistent today. The corner-radius control Karl mentioned applies to Button Blocks and Continue Blocks, but the Start course button doesn't have that same option, which is why you've had to maintain a script that gets reapplied on every export rather than something you set once.

I don't have a reason to share for why it's inconsistent across button types, but the gap you're describing, and the recurring workaround it forces, is a fair thing to flag.
