Create a reconciliation template and an account template and build a link inside an infotext on each of them that connects to each other. See the image below as an example:
Tip: Remember to put a handle when creating the reconciliation template and to refer to the particular account number where your new account template is being used.
Solution:
In the example below the account template is used in the account 100000 and the handle recon_template was created for the reconciliation template.
Reconciliation template code:
{% ic %}{::infotext}{% linkto period.accounts.100000 %}Account template{% endlinkto %}{:/infotext}{% endic %}
Account template code:
{% ic %}{::infotext}{% linkto period.reconciliations.recon_template %}Reconciliation template{% endlinkto %}{:/infotext}{% endic %}
