Sole Proprietor as GST Practitioner

Can a Sole Proprietor of certain business engaged in reselling activities and also registered as tax payer under GST apply/is eligible to become GST Practitioner?

If yes, then after getting such license, does he need to get 'Tax Practitioner' added under the scope of work in his Shop Act license?

I am from Pune, Maharashtra.

Thanks & regards,
