After beating Hardened Ursa:Luna, can the Superpowers reward be used as many times as you want or only once?

There is a checkbox available to you after defeating Hardened Ursa:Luna. When checked, all powers except ML (likely due to its corresponding advancement maxing out at 5) can be used as superpowers, which double the effect of each power in a stack (A stack of powers is 5), at the cost of using the whole stack.
FCSP is simply a cache of size 1000% of every type.
SACSP and SMSP supercharge for decuple the length of SACP and SMP. (Decuple being x10)
TWSP advances time by 10 hours.
MRSP conducts a market raid of size 1000%.
FBSP reveals 1500 fogged territories on the map.
IMSP inspires a mercenary camp as though there were 10x as many mercenaries in that camp.
SLSP allows you to start 10 levels higher on the main menu than you currently can.
MLSP, well, doesn't exist because its advancement only goes up to 5!

cool, then i will actually go and beat that level, thanks!
