Using Variables Within Button Actions

I am using a large number (21 presently, growing later) of buttons on one particular sheet,
and rather than specifying B1.Visible = False .. B21.Visible = False, can I use a For statement somehow?

For Butt = 1 To 21
    ("B" & Butt).Visible = False
End For

Also, all these buttons will be assigned variables based on their unique functions before referincing a generic function. i.e.

'Each Button pressed disables the previous button

("B" & (Butt - 1)).Enabled = False

Is there anyway to do this, or am I going to have to do it the long way, of copy and paste 21 times and renaming?

Any assistance available?

Thanks!
