Bulk Convert Leads to Contacts

[GrokWhy]

Is anyone aware of a method to convert Leads to Contacts in bulk?

We're using this to manage volunteers.

If not, do you think the Advance Pack add-on could do it?

Thanks,
Russ

I initially though that you can just "mass update" it but it look like that not possible, currently it look like only individual click.

I don't use Advanced Pack so not sure but considering the powerful that Advanced Pack is, I think it is possible.
