look at using the tablearg option with the pipe command.

1900 pipe tablearg all from table(1) to any
1902 pipe tablearg all from any to table(2)

should allow you to do it all in 2 rules if you set up the table 
correctly.

Tablearg in not mentioned in the 'pipe' command help entry but pipe IS 
mentioned in the tablearg section.
let me know if it works!
