In order to combine Ex with Ey you needs to generate Newmark combinations. You can automatically generate this type of combinations in two ways: you can load the NEWEC8.cbn from Loads CBN and then generate simplified combinations, or you can generate detailed combinations and check that on the parameters dialog box the Newmark combinations option is checked.

When you create a new seismic load, a new Modal analysis will be created. To impose masses eccentricity you need to go to Modal analysis=> Properties=> Dynamic masses eccentricity. Now you can choose if you want to use eccentricity, on what direction you want the eccentricity to be applied and the value for the eccentricity.( see picture)
