Series linked to speaker

Hello
Does anyone know how to link a series to a particular speaker?
On the speaker's page, I have a list of semons (some of them belonging to series) but when I click on "Series" on that same page, it says "Sorry, unfortunately I didn't find any Series". It seems then that the series are not linked to that speaker.
I hope that makes sense...

The link goes over the sermons. So it should show all series where that speaker had given at least one sermon.
It may be that there is an additional filter active in the menuitem. Eg a category. That would apply also to the series listed.

Does that mean that the series and the speaker have to be in the same category?

In the current version, I think it has to be. Since the category isn't specific to the item type.
I intend to change that behaviour with the next major release so you can have categories specific for series, speakers and sermons respectively.
