Note: I used Google Translate to try and see your issue, I hope I understand the issue
If you are using Adobe Launch, you should be able to configure your page view event differently from your click event.
If you mean you are sending an extra "action" on the page view to capture a specific value, there is no need to do that.. you can set a value on your overall page view event that only contains value of "field A" when certain criteria are met... and on the click, you can target the specific button for the click and populate "field B" when that click happens.
I hope this helps.. I am not sure if it's specific enough for your needs, but the language barrier is challenging.
