How do I update an ask amount for a donor?

If you want to update single contact's ask, you can do so in the profile of the contact by selecting the pen icon next to the ask as you scroll over the ask amount. You can update the ask amount and/or the ask notes field at the same time. 

If you would like to bulk update asks for multiple donors, you can do so either by filtering down your list from the contacts page, and bulk applying an ask using the bulk action checkbox on the far left.

You can also bulk update or individually update an ask amount from a calltime list. Additionally, you can also perform a  bulk contacts import with an ask column with the new ask amount for each donor and it will override the existing ask amount.
