Is there a DIR recommendation on type or siting of drysuit dump valves?

The reason I ask is that I'm having problems with mine (old style high profile Apeks autodump) as it seems to be in the wrong position - further forward than it should be, I think, when I'm horizontal in the water it's maybe 3 inches below the highest point of my drysuit sleeve. As a result when I'm ascending a big bubble of air collects around my upper arm / shoulders, requiring some major contortions to dump it. Therefore, I'm thinking of trying to have it moved, or fitting a cuff dump as well.

I think I remember reading somewhere about one or more GUE instructors having autodumps on their wrist / forearms. Is that correct, and if so what's the reasoning behind it?

Being a newbie it's possible (likely?) that my problems are a result of poor trim/technique, so I'll persevere for a bit and try to get it sorted. But in case I do need to change the valve, it would be really useful to know if there is a DIR position on this and if so what the reasoning behind it is. Thanks in advance for any info.

PS I'm diving with minimal air in the suit, just enough to take the squeeze off.
