Delete connection nodes > delete referenced features > yes to all

[leendertvanwolfswinkel]

If you select a group of connection nodes which are connected by channels, and delete them, you will first get a single popup asking you to if referencing features should also be deleted. Then, you get this popup:

Which makes sense, because all channels have cross section locations. If you click delete all referenced features, you will get this popup many times (1 for each channel?)

Desired behaviour:

• 1 popup for 'features referencing connection node(s)'
• 1 popup for 'features referencing channel(s)'

(example: Meerssen dataset)
