Checking information using nested invoke methods - How to jump out and go to next item in loop

Hi,
I am using an invoke method in a for each loop to iterate through excel sheets. The invoke method includes another invoke method. The first invoke method checks if certain information is given in the sheet and jumps out if anything is missing, the second invoke method checks if a date given in the sheet has the correct format, corrects it and checks if it is a valid timespan (From Date < To Date). If this test fails I need to jump out (two levels) and check the next excel sheet (next item in for-each loop).

To leave the first invoke and continue the try catch activity combined with a terminate workflow activity worked well, but what can I do if I need to “jump out two levels” (in the 2nd level a mistake is recognized)?

Thanks for your help
