How to remove a point from an edge in LW?

Hello,
Ive got a basic question about lightwave modelling:
Trying to learn by modelling a head, now I tried to turn it all into subpatches to see what I've got.
Sadly one polygon does not turn into a subpatch.
This is because it has 3 points on one of its edges (2 points + one somewhere near its middle) =>

| < polygon 1 > | <=== this polygon wont convert
.______.______.
| < 2 > | < 3 > |

My question is, is there some way to dis-associate the point from the edge?
So that it can be converted into a subpatch?

Googled my bum off before turning here.

Thanks a lot!
