What is multislot already attorney?

Hi,

When asked for LCA processing I got following reply from my company visa department:-
"Multislot already attorney will be having a certified LCA for few locations hence for those cases BRM/Managers/associates will not get the filing notice. Directly petition will be filed with the USCIS"
What is multislot already attorney? and how will I come to know about my LCA processing?
Will it have any effect on my H1B petition filing?

It will not impact the outcome of H-1 petition. It is normal to cover multiple locations in the LCA.
