You can
use the automatic review assignment function and also assign submissions for reviewing both before and after that process manually.
Already assigned reviews will never be changed by the automatic process.
However, you can refine the results of the automatic process manually.
You can
assign contributions to reviewers manually on this page:
Overview => Submissions & Reviews => Program Committee and ReviewersIn the right-hand column "Action" click on "Assign Reviews".
From the list of all submitted contributions, check the box "Assign" if you want to assign this submission to the reviewer (see image 1).
Then
assign the remaining contributions to reviewers automatically (see image 2):
Overview => Submissions & Reviews => Automatic Assignment of ReviewsYou can choose from a number of specific options and filters.
This assignment function will automatically consider preferences of reviewers entered by them.
We recommend using both functions depending on your requirements.
After having assigned submissions automatically you can use the manual assignment again to test the result of the automatic assignment or to further refine the results of the automatic assignment.
