For the creation single select list we have:
<input-field type="single-select">
<name>currentCountry</name>
<label>Current country</label>
<required>true</required>
<options>
<option>
<id>..</id>
<name>...</name>
</option>
<option>
...
</option>
</options>
</input-field>
But what if we want to show the list of countries that already exist in SW?
Can we specify the source of the entity so that it can be transformed into the desired format? In Magento 2, we have such an opportunity, does SW support something similar, or is it possible at some stage to substitute the necessary data there so as not to form a permanent list in xml?
