enable ccpro features in ccstd

System

In the OOB ccstd, user can't tag multiple files at the same time because when the files are listed, there is no checkbox for you to select more than 1 files. So I started to play with the UITK and I was able to add the list_my_workareas link from ccpro to the ccstd directory list heading in ui_custom.xml:

<heading id="iw.ccstd.list_directory.dirlist.heading">
<link id="test.ccstd.list_directory.list_wa.link" refid="_iw.ccpro.list_my_workareas.link" />
</heading>

This gave me the checkboxes when files are listed. However, since the ccpro "File" menu is not here in the ccstd, I can't tag files on this page. So I tried to add the following to the ui_custom.xml:

<heading id="iw.ccpro.list_directory.heading">
<link id="test.ccpro.list_directory.tag.link" refid="_iw.ccpro.list_extended_attributes.link" />
</heading>

And only to find out that the "Tag" action would not show up in the heading. Does anyone know why this link does not work in headings?

Any suggestions on a better way to enable tagging of multiple files in ccstd?

Thanks in advance!
