Dotted Fixtures

Is it possible to add dotted fixture numbers to a whole bunch of fixtures in one go.

So if I have 20 generic dimmers and I want to create 2 fixtures of 10 is there a syntax to do it in one go as apposed to 1.1>10 then 2.1>10

I realise the syntax is say 1.0 but I want to apply the dotted fixtures numbers to a lot of fixtures at once.

1.1
1.2
1.3
1.4
1.5
1.6
1.7
1.8
1.9
1.10
2.1
2.2
2.3
2.4
2.5
2.6
2.7
2.8
2.9
2.10

I have hundreds of units to do and can't seem to make it happen!
