It is possible. To change the title of a training, load it from the Training Log and then edit the title.
I think the fastest way to get all trainings exported as CSV is to have the device connected by ActiveSync: export one training, rename and copy it to your PC and then export the next one.
Is it possible to change/add titles to existing trainings?
It is not easy to find new names to all trainings :-) Perhaps the programmers could ad a datestamp to the title of exportet files?
No, that's not possible. If you enter a title for the trainings, the exported file will be given that name, so you would not have the overwriting problem.
I have tried to export old trainings to csv. The problem is that all trainings have no title: "unnamed". Exporting one training will owerwrite the existing one! How can I prevent that?
It would be perfect if one could convert/export multiple tranings in one step - is that possible??
