Convert custom character preset to a morph dial

Banyan

I purchased a custom character that I like that only has a head apply/remove and a body apply/remove. Is there a product off the shelf I can buy that will help me convert that to a dial so I can only use it at 50% or something? Or if there is no product, an easy to follow set of steps? I did some searching on this but the method I found looks pretty old and may not be the best way anymore. If it matters, The custom character is a G9, but I'd like to be able to do that with a G8 as well.

For creating a single Control Dial:

1) In Parameters pane, right-click to turn on Edit Mode;
2) Right-click in Parameters pane again > Create a New Property. Give it a Name / Label, set Path as Actor/People/Feminine or Actor/People/Masculine, Type as Modifier/Shape, Min as 0, click Create button.
3) Dial the head and body morphs on Genesis figrue. Right-click on the newly-created property > ERC Freeze.
4) File > Save As > Support Asset > Morph Asset(s) (Modifier Asset(s) if you use DS 4.23+). Locate and check the above control dial ONLY ! Click Accept button.
