Hi there.
Sure, this can be accomplished.
In this case use your homepage with all the keywords you would like used for it specifically as the Destroy Your Competition Module.
For the inner pages please post each url with the keywords directly underneath, and separate each url/keyword combo. I would need a minimum of 10 and a maximum of 20 such url/keyword combinations in this case. The maximum is due to the fact that when using specific keyword url combos, each would need to be set individually with its own submission task. If it was all keywords to all urls, then just one task would need to be set, and that's why unlimited urls could be used.
Please let me know if you have any other questions about the process.
Thanks.
