Multiple data sets in one cloud

Is it possible to load two distinct data sets into one cloud and have each data set retain independence (e.g., have separate color)?

For example, both data sets might contain the word 'dog', but the first data set has 20 occurrences while the second only has 5. Would like the terms in first data set shown in blue (so the first dog would be large blue letters) and the second data set shown in red (so second dog would be smaller relative size to first and in red). All this would appear in one cloud.

Hello, it is possible if you use CSV format when importing words.
Create a text file with the below content

1 set 1 word;20;blue
1 set 2 word;20;blue
...
2 set 2 word;5;red
2 set 2 word;5;red
...

And then import the text using the corresponding button in Words section.
