Add command to change "Date added" values

[AlbatorV]

I use collection at job with folders, grouped by status (labels) and instead of following since when I started to process, "Date added" column is perfect for me.
But this new column is added since 13.16 beta 6.
So I need command to add date to folders added before this version.

In file collections a new column, Date Added, is available. This displays the date/time that each item was added to the collection. Note that existing collections do not contain this information so the column will not display data for any files added to collections by earlier versions.
