+    scan_dispatchcheck(conn::DbConnection; reasons = NamedTuple[])
+
+Interactively scan PS Boards to check they passed the QAQC.
+If the board have suspicious results but actually passed the test, you can select one reason for that board or
+add new reason to explain.
+
+# Arguments
+- `reasons::Vector{NamedTuple}`: reasons why given board passed the test. This is *mutated* during the session.
+
+## reason structure
+
+One element of the `reason` should be like this:
+
+```julia
+(
+    name = "name of this category",
+    passing_pairs = NamedTuple[
+        (; psboard_id, note = "supplemental note"),
+        others...
