I wouldn’t worry about it too much, eventually you are going to get comfortable enough that you’ll be able to do 3-pointers and wheelies interchangeably on the fly without really thinking about it.

Try this: about halfway through your flare, ease in just a hair of forward pressure. A wheel landing on the back side of the mains.
Funny story about this.
Tuesday dawned severe clear here in the PNW which caused me to develop an eye problem (can't see going in to work). I figured it was one of the last clear days around here until, oh, July. I went to the airport with no plan at all other than aviation. Eventually I decided to fly up to Arlington to see if they could repack the Softie parachute that came with my plane. Long story short, my chute was too old but they'll give me a great trade in when I have money falling out of my pockets.
On the way home I made a nice full stop and taxi back at Langley (W10) which is a great strip if you want to see how well your butt cheeks gather up a seat cushion.
Then I made my way back home to Tacoma where I asked for some closed traffic. On my third lap of the pattern I decided to quit before I messed up my record of five greaser 3-point landings in a row.
"There I was.."
Short final and looking at 65mph indicated, which is about 5mph too hot for a good 3 point in my plane. A perfect time to demonstrate my ability to convert to a wheel landing spontaneously. So I got there exactly as described above, in a flare and all I had to do was ease off on some back pressure and land on the "back side of the mains" (a strange expression but it describes what it feels like perfectly).
Damn if I didn't flare about a foot high, and my 8.50x6 tires bounce like a basketball. I went from Cool Hand Luke to yard sale in one bounce after that nose pitched up. I rescued it with just enough power that I chose to log the second bounce instead of the first.
I laughed at myself all the way to the turn off.
So I guess I'm not there yet.
