Grouping similar events

Hey,

we use sentry since this week and we have some errors they are have the similar but not the same stacktrace.
In most cases the stacktrace has only one or two differences, but its the same file, line and error (message).
Can we group this directly or must we merge it manually?
We are using Sentry 20.7.0.dev (056b6cb3).

Here is an example: https://i.imgur.com/KaBgGJ4.png

Thanks for help
