Juniper interface ranges

So I started a new job this week and they use Juniper for switching. I've mostly used Cisco so I'm trying to figure out the Juniper way of things. When setting up a switch (EX series in this case). I've found that you can specify a range of interfaces to bulk edit similar to Cisco, however, it seems very cumbersome to change it later. Do I just delete the whole range and re add it (this is what I've found so far but this seems wrong to me). For example, ports 0 - 20 are on vlan 5, but later port 0 is changed to a trunk port. What is the proper way to handle this? Is there a way to edit a range of interfaces but they still appear as single interfaces in the config (like Cisco)?

Thanks for the help!
