Add ability to create file group in file browser
The ParaView file browser looks for files whose name matches a pattern and groups them together. When the group is opened in the file read dialog, the list of files in the group is sent to a single reader where it is interpreted as a time series (or other convention based on the reader).
The file browser grouping usually identifies groups of files, but may fail if the pattern is unexpected. In that case, it is impossible to open the collection of files as a group. If you attempt to select them all and open them, ParaView creates a separate pipeline object for each.
There should be a way to select a collection of files and create a custom group out of them so that the group can be loaded into a single reader.
