Hi,
Welcome to Toolset support, If you want to achieve this, Submit Alumno ➜ land on that Alumno’s single page ➜ show a Memoria form there that is already linked to this Alumno and pre-filled with the Alumno’s Camada.
Then you need to do as follows:
Step 1 — Alumno form
Build a normal post form for Alumno and include the Camada taxonomy field.
Step 2 — After submit action
In the Alumno form Settings → After visitors submit this form, choose Go to the post (i.e., the newly created Alumno single).
Step 3 — Put the Memoria form on the Alumno single template
Edit the single-Alumno (or its Content Template) and insert the Memoria create form on that page.
Step 4 — Auto-link the parent (Alumno)
In the Memoria form, include the relationship/parent field (e.g. @alumno-memoria.parent) and set it to use the current post as the parent.

Step 5 — Pre-fill Camada on the Memoria form from the current Alumno
Add the Camada taxonomy field to the Memoria form and set its default from a shortcode that reads the current page’s term (the Alumno page you’re on). For example, set default to the term slug via:
[wpv-post-taxonomy type="camada" format="slug" item="$current_page"]

Now, the User creates Alumno → WordPress opens the new Alumno page → the Memoria form on that page already knows the parent Alumno and has Camada pre-selected to match the Alumno’s Camada.
Thanks.
