Arc Slot with a radius edge won't allow auto centre lines

Hello,

I have several slots cut into this panel which then have a 4mm radius on them, if I suppress the radius then I can add the auto centre lines.  Once the radius is applied and shown on the drawing it only recognises the fillet or original boss extrude as features I can dimension.

Out of interest is there a way to use hole callout on an arc slot?

This means that it only adds the centre marks to the end radius and centre individually, I have been editing these to make it look right but I thought they might be an proper solution.

This is what I would like to do but

with the radius showing

This what happens when the radius is showing,

I currently just shorten the middle centre line.

Thanks

Adam
