Sri:
Actually the thiruman and srichurnam are not coming under basic shastras,
it is a developed shastras may be come under sampradayam.
Anybody who is having the knowledge of dharma shastra can suggest you the correct rule for things coming under shastra
but it is difficult in Sampradayam.
Some are saying yes and some are saying no, there is no written evidence.
My suggestion is NO.
