Razer Tartarus V2: Unlock programmable "second" Funtion to keys

Razer Tartarus V2. You say there hare 32 fully programmable BUT for my playstile i need more! Let me explain better: I have been playing SWTOR for years, the functions I need, to avoid using the "normal keyboard", are MORE than those that can be mapped on the 19 programmable keys; but many are optional.. On the normal keyboard I use the "alt" key for double the function of the "same" key. I'm sure you could do the same here too, but the software doesn't allow it. What I need is that by pressing a key "Alt" the macros mapped on the keys are DUBLE, one from 1 to 19 and another from 20 to 39 in the same key but with different functions. The acqtual "alt" button seems perfect for this assignment .. It would be enough that when the programmable keys are pressed they will change .. This function is standard on other similar keyboards, here it is missing! I hope I explained to myself, otherwise I could give examples. Thx for any answer
