How to specify merge stratergy

[maddy302]

I am eager to define a merge strategy for merging a pull request. The current service I wrote, when encounters 2 PRs to merge, one gets merged, the other one ends up in error

"Merge Exception, New changes were pushed to master in xxxxx while the merge was being performed. Please retry the merge"

I see the web api uses stratergyId as a param to decide which strategy to use to merge.

Is there a way we can do the same for bitbucket server.

I am on Atlassian Bitbucket v6.10.1 (server)
