how to default ''expand'' assignment groups in dispatcher workspace?

[Joshua Chen MTL]

is there a way to keep the assignment groups ''expanded'' so that i can always see the technicians under the 2nd groups?
everytime i click on a new task or rerfresh, it collapses the 2nd group

g_aw.setSectionExpanded

For more details about the documentation of this method , check below
