Upsell App for personalized products?

[MotorMemories]

Hello Guys,

iam looking for an upsell app that allows me to upsell / cross-sell personalized products.

My store URL is: motormemories.de

The Plan: i want to upsell the product "personalisierte Handyhülle!" after someone is making a purchase on "Erschaffe dein Kunstwerk!" -> look on the website and you see the mentioned products in the header.

Iam very thankful for any help.

Greetings from germany
