Has anyone successfully programmed their Garmin Edge for pyramid intervals? Seems like something that would be easy to do, but I run out of "steps" in Garmin Training Center when trying to do this. What I want to do is something like this:

1 min hard riding
1 min rest
2 mins hard riding
1 min rest
2 mins hard riding
1 min rest
3 mins hard riding
1 min rest
3 mins hard riding
1 min rest
3 mins hard riding
1 min rest
Repeat this pattern through 5 minutes...

Has anyone else been able to do this with their Edge ( I have a 205 if it makes a difference ) ? Thanks in advance for any help.
