Flexible "add via points" function in "route and measure" track design.
Actual: by config .cfg: Choose a prefered fixed setting.
New: If no via's is prefered modus, allow to place MUST PASS VIA by a second +tap at the same location. A single first +tap adds a "soft via" -> next +tap at same position a change to "hard VIA" -> a next -tap at same position back to "soft via". Save and keep the hard = MUST PASS VIAS only in finalised trackdesign.
