Connecting multiple grids simultaneously in OpenACC

Good afternoon colleagues, please tell me with OpenACC. I have 2 arrays that I want to fill as quickly as possible. I divide each array into a block-thread tensor in which a fast parallel calculation takes place. However, the two arrays themselves are most likely not filled at the same time. What are the ways to, for example, run these two arrays simultaneously, say, on 2 grids at once. And in general, is it possible to manage grids and their launch in OpenACC?
