Also clear logo cache on TV guide clearance

In the settings of PVR you can easily clear the tv guide info, which is useful… but you cannot clear the tv logos this way.
Wouldn’t make it sense it also did this?
TV logos change over time, I sometimes update my logo’s with my own logo pack I maintain and right now there’s still 1 year old tv logos in my cache.
It’s just logical one would search for it at the same spot where you could clear the tv guide data.
