Change Attribute - Configuration Item mapping in Scriptable Task

Hi,

is it possible to change the mapping of attributes to configuration items with a scriptable tasks?

Or do I have to map all possible configuration items to attributes to decide later which one to use?

example:

configuration 1:

cpus=4

memory=8

disk_size=16

configuration 2:

cpus=2

memory=4

disk_size=8

Is it possible to have only three attributes (cpus, memory, disk_size) and map either configuration 1 or configuration 2 via scriptable task?

Or do I need 6 attributes (cpus1, cpus2, memory1, memory2, disk1, disk2) do a static mapping and use three of six possible attributes?

Thanks,

Michael
