Well it can... but not with a bound optiongroup. She'd have to have an unbound, i.e. no controlsource, and then somewhere in the validation say

replace nDow in (cAlias) with this.value+1

and in refresh

if between(cAlias.ndow,2,6)
this.value=cAlias.ndow-1
else
this.value=null
endif

...or something of the kind. Don't know whether this is any simpler than the hidden Saturday optionbutton kludge.

I'm actually amazed that the first day of the week is not universally Monday. In Slavic languages, the names of the days are pretty much numbers - Tuesday is Utorak, Torek, Vtornik - from vtori, second. Sreda (wednesday) means middle (ha!- that makes Sunday the first day, we got a contradiction), chetverg, csütörtök (that's Hungarian), chetvrtak - Thursday, from chetri, chetire, shtiri - four; petak, pentek, pyatnica (Friday) from pet, pyat - which is five.

I guess back in old days they weren't that strong with standards, eh? Even within Christianity they couldn't get the week straight - if the so-called creator rested the seventh day, why would that seventh day be the first in a thus defined week, makes no sense to me.
