Short answer - Yes, But all ports will have to be trunk to allow both vlan traffic.
Select the Admin mode - 802.1Q Trunk
Trunk-Vlans allowed ( Add both 1 and 100 ) - 1,100
From the device console you can use the range command to do the same.
I have some additional questions
1. Why do you want all ports to use both vlans, is one of them a voice vlan ?
