May one have in mind not to be yoitzeh krias hatorah in a minyan that he is participating in order to be metzaref for another minyan later?
For example (according to the opinion that on Mon,Thu you only need 3 people who haven't heard kriah to make another minyan of kriah provided you have another 7 to be mashlim the 10) can someone who is part of a 730 shacharis minyan have in mind not to be yoitzeh the kriah if he knows at 830 they will need him to be one of the three who havent heard kriah yet?
Thanks
