Filter by IP address list

In Winbox → IP → Firewall → Connections → Filter
the “in” or “not in” operator suggests that it can be followed by a list of elements; in my case “Src. Address”.
Please see attachment.

How can I indicate more than one element?

I tried with various separators (comma, semicolon, space) and enclosing (or not) everything in brackets without success.

v.7.16.1

Haven’t tested, can you add more lines? By using the + simbole and using the same field to filter on?

Use cases please, will give us some context.
