When mapping an input property to an Umbraco.MultiNodeTreePicker export property you have to format the input string as a comma-delimited array of strings. Like this: "thing,other thing,something,not a thing".

CMSImport is taking that string and splitting it on the commas and then checking each substring against node names in the CMS.

It would be extremely helpful if during the mapping process one could define what the delimiter is. For example: a comma, a semi-colon, or a pipe.

The reason for this is because the Umbraco CMS allows commas in node names! This causes a huge problem when trying to map the input csv string to the node names in the CMS.

As an example, let's say we're mapping a list of authors. If the input string looks like this:

"John Doe,Jane Doe,Jack Doe, Jr."

And our node names in the CMS are these:

John Doe
Jane Doe
Jack Doe, Jr.

CMSImport is going to split the string into these separate substrings:

John Doe
Jane Doe
Jack Doe
Jr.

And obviously our values aren't going to match. But if we could define the delimiter ourselves then perhaps our input string could look like this:

John Doe|Jane Doe|Jack Doe, Jr.

Thanks!
