Default nextbook 8 google play install

I have the nextbook 8 amlogic that I have rooted with cydia impactor. I don't have google play and would like to install. It took me a long time and finally read about cydia. I have finally got my tablet rooted and would like to keep it that way. Is there anyway that i can just install google without having to reroot again. I found xda forum for rooting and rom for google play but is there anyway I can just install google play now that I'm rooted. I'm not that technical savy. Please any info on this will be greatly appreciated.
