Hi Sabuj,
There is no user interface way to do that (you'd have to get into code)... however, your question is quite timely, as there is a new plugin that provides a Rotamers-type interface to hundreds of nonstandard residues.  It also makes a new command "swapnaa" to access these residues via command line.

This SwissSidechain plugin is provided by the Molecular Modelling Group at SIB.  Information and download:

You can browse the SwissSidechain database to see if it includes your residue of interest:

I hope this helps,
