git branch - How to partly merge branches in git -

i have 2 branches in project:

master | develop ------ | ------- abcd | bcda7 | bcda6 | bcda5 | bcda4 | bcda3 | bcda2 | bcda1

how can partly merge branches? let's merge commits bcda2 - bcda4 master (i don't need merge commit bcda1), merge commits bcda5-7 master?

i know how utilize git-cherry-pick don't wanna utilize creates new commits , there mess in future merging branches. i'd retain current commits ids , partly merge branches.

i tried utilize

git rebase -i

i removed lines pick bcda5 - pick bcda7 hence merged branches removed commits bcda5-bcda7 completely.

could please advise on how correctly?

git git-branch git-cherry-pick
