Membership Combining Access Level To Show Content?

Hi, is it possible to combine access level shortcodes to show content?

An example of the situation I'm trying to solve:
[level1]
show content of level1
[/level1]

[level2]
show content of level2
[/level2]

[level1-level2]
show content of both level1 and level2
[/level1-level2]

I have tons of drip-fed levels and wonder if its possible to do [level1-level2] as in the example.
