Let us decide the Level of the Skill we want to make when we have a higher level skillgem

Its extremely fucking annoying that you either have to farm or buy a low level Skillgem when you need a lower level of the skill because your attributes are not high enough. Let us decide which level the skill should be while we create it. So if you have a level 16 skillgem you can for example make a skillgem with the level of 8 without using a Level 8 skillgem.
It wouldnt impact the economy at all. Skillgem make up a miniscule fraction of the economy.
