World generation setting

I am struggling a bit to find a world with just the right amount of mountains and hills.

Could it be possible to have 2 sliders for that upon world generation?

Like one primary and a secondary.

If primary is set to i. E. High mountains, Huge mountains will be created.

The secondary slider set to low, would cause that each high mountain is surrounded by flat lands.

That is what I would be looking for

Another example:

Primary set to low/flat and secondary to high could cause volcano like areas with a caldea in the middle.

Basically the primary slider defines a few spots on one island, while the secondary defines everything between the area set by primary.

Could also work on ocean level, so even in the ocean area single peaks could pop up every now and then
