I'm trying to figure out a way I can count the amount of appearances of certain letters within a cell, and/or just mark true/false if any of the letters appear

Example: looking for (a,e,i,o,u,v,m)

abcde = true (2)
bcddr = false (0)
bcvwr = true (1)
bamvg = true (2)
xrwpt = false (0)
mxrpm = true (2)
aaaai = true (5)
vvvvf = true (4)
axaxa = true (3)
zzzzz = false (0)

How can i do this without having to count each letter individually? I've seen this question asked similarly, but only for individual letters, and in this case, i need to search all at once.
