Hi,
Origin do not have such options for label -p, but I think you could try the selection command to align the objects, for example:
label -p 50 50 -n text1 AAAAA;
label -p 20 70 -n text2 BBBBB;
page -sa text1;
page -sa text2;
select -a r;
select -a: https://www.originlab.com/doc/LabTalk/ref/Selection-cmd#-a.3B_Align_objects_according_to_the_specified_parameter
page -sa: https://www.originlab.com/doc/LabTalk/ref/Page-cmd#-sa.3B_Select_the_specified_object_on_the_page_and_preserve_the_status_of_all_current_objects
Hope it can be some helps!
