SMC How to support paper correspondence and increase no of characters in custom text field

Hi,

Besides email campaigns I need to support a campaign process that includes prints.

In SAP Marketing Cloud I create a campaign with a file export for label printing and in addition the creation of a taks in order register the interaction.

As call center agents need to have insight in the content that is shared with the customer, I need to store information with regards to the message sent, especially when it concerns a letter.

In the campaign description and task description and notes I can add some text but the number of text I can enter is very limited: 170 characters.

I also tried to create a custom field of type Text, the number of characters has a maximum of 500

Is there a way to increase the number of characters? Or has any body a creative suggestion

Kr.
