There is no way to remove the dialog but we are working on an enhancement to extend the amount of "hours" you can enter there so you can do longer due date lengths like you mentioned.

I encountered the same situation. The way I worked around this was to setup the work schedule options for a 40 hour week at 8 hours a day then when you set the due duration to 16 hours it acts as 2 days. This method will get you up to 12 days using 96 hours. In your example you would have to select the created schedule in the Work Schedule dropdown when you configure the priority. I hope that helps.
Thanks, I ended up doing the same. Extended the hours out another digit should help our cause. Having the option to set a default could be helpful as well.
