I dont think that is possible? What do you mean solomining, like without a pool? You know nicehash is a pool right? A pool that rents out hash power. Maybe if you try to explain abit more we could help you on your way with what you mean 
Yes. solo mining without pool on my PC & my own wallet.
Is it possible point out a rented hash to my PC for Solomining?
Lookup Sammy 007 proxy on github. You can setup on local server. There are several. You basically need a way to process work that the rentals can understand. Also lookup whatthefluxable 3 part series on bitcoin mining pool setup. Its a good one and also covers many coins Another would be NOMP. There was a windows one as well that ran on executable once config was setup. Easy but need a dedicated rig for that. Seemed I had trouble with it. Im sure its come a long way over the years tho. Sorry I cant think of it atm
