Wedding party entrances

My MOH is no longer in my wedding for reasons I do not care to discuss. I am trying to decide the best way of arranging the bridal party now. I know it’s more common nowadays to have an offset number of bridesmaids and groomsmen. For the ceremony I plan on having the officiant take his place and then the groom take his place and then have the best man escort the grooms grandma (which is also his grandma) and then he will take his place after. Then everything will be as normal as far as the rest goes.
However, for the reception when the DJ introduces the wedding party the best man will not have anyone to escort. My parents will be announced together, grooms parents will be announced together and then everyone else will have a partner just not my best man. I considered having him just come out by himself which I’m sure he would be fine with but I don’t know what, if anything he could do or how the DJ should announce him…. Or if there was any other ideas someone could give me to help that would be appreciated!!!
