Custom field(s) on Tasks + Mass updating on those custom fields

Custom field(s) on Tasks + Mass updating on those custom fields

Hello,

I am about to upgrade to one of the Zoho Crm versions, but i do need this functionality to be possible (for certain to work) (i cannot find it clearly in all online help) :

- creating custom (text)fields on Tasks
- mass update on those new customfields from ListView (via MassUpdate button)

My question is :
- is it possible to create custom fields on Tasks - and from which version on of Zoho Crm is that possible?
- which fields on Tasks can be MassUpdated? (limited, or all standard & custom fields?)
- how many custom-fields can be created on Tasks (and other modules)?

Thank you for your help!

Best regards,

Yannic
