Player Potion effect lvl

[Blackarr]

it would be great if there would be a way to get the potioneffect lvl of a player it is currently not feachable.
or to check if the player has the potioneffect + lvl.

for example
%player_potioneffect_lvl_% -> returns the player effect lvl of the given effect
or
%player_has_potioneffect__% -> returns a yes if player has the given effect on the given lvl
