Automatic merge like gitFlow

if we have some example branch model based on gitFlow and automatic merge option in Bitbucket is on:

master
release/2.0

release/1.0

develop

and we create some "test" hotfix of master automatic merge after pull request will add changes to:

master -> develop

that will be really nice if automatic merge will be add changes to releases too like:

master -> release/2.0 -> release/1.0 -> develop

or maybe is some possibility to do such automatic merge now ?
