This can be done in the ISN with just a few modifications to your order form.
First, navigate to Settings -- Office Settings -- Customize Order Form. Locate the section you want to add this additional date/time to, and click the ‘Controls' button on the row for that section. (Click here for more information on customizing your order form)
Then, you will need to add 3 new controls to your order form – you can name them whatever you want.
A Drop Down Box (Named something like ‘Additional Service Requested’ or ‘Vendor’)
A Date Picker (DO NOT select an additional ‘Inspection Date/Time control’ doing so will cause problems)
A Text Box (Named something like ‘Additional Service Time’)
Once those have been added, you can arrange them to your liking by clicking and dragging them with the small ‘hamburger icon’ on the left side of each control.
Now those controls will show up when you view your order form, and you can include those values in any emails by using their custom replacement values in any email you want! (Click here for more information on those replacement values, and click here for information on editing your email templates)
Also, this additional arrival information will show up in your mobile app as well. If you view the inspection information in your mobile app, then click ‘View All Details >>’ you’ll see that information in there as well.
