Additional attachment purchase options

Additional attachment purchase options

I see many post, some over 8 years old asking for a way to identify attachments in the CRM.  It appears no solution has been offered by zoho other than do it by hand or pay $960 for 100 GB of space.  Why cannot we add space in smaller increments?  It took me four years to reach 10 GB and now I have to purchase and additional 100 GB.
