When constructing a subset with the subset creator, I think it could be interesting to get have more option in the data filter. In the 'slice operators' section you can choose an operator to filter your data, but it could be great to have an operator 'like' that support regex syntax, it could be usefull for the criteria 'String' (even for other criteria, because number are supported in regex).
Thank you for your great idea. While we cannot commit to a specific target version, we will consider adding it to our future internal backlog. If you can add further information about the context of this feature, please add it here so we can evaluate it more fully.
