Is it possible to review pull requests since last reviewed without displaying merge commits ?

[limeryls]

When a pull request is opened and an other branch is pulled on the branch related to the pull request, the merge commit is included to the "Changes since you last reviewed".

Is it possible to ignore the merge commits in the review or must I use an other process for reviewing changes ?

My process : 
 - Create a branch from develop for make changes
 - Make some changes on the newly created branch
 - Create the pull request from the branch and develop branch
 - Wait reviews from others team members
 - Make some changes if reviewers don't agree with me code
 - Pull develop branch if newer commits are existing
 - Mark my work as becoming reviewable again

If newer commits exists on the develop branch, some "merge commit" are available in my pull request and "pollute" the review (especially when a feature has been merged).
