Call and load work with a specific concordance and group preset in concNav

[nikobeer]

Sometimes it is not "the work" that you are interested in but its "components" (like a specific song within a work that is a collection of single components = song collection). So, when providing entrance points to edirom editions based on component lists (alphabetical list of songs that are organised within different song collections) it would be nice to be able to preset concordance and concordance group in concNav.
