Import only specified record

Hello.

First of all i want to say that you have an excellent plugin.

Besides wp all import i’m using WP All Import – Real Homes Add-On.

Now to the question.

I want to ask how and if i can import properties that are using a specific field in the XML. For instance: The XML i’m using has all features,images,location etc etc. and there is an extra custom field named <PSIG> YES </PSIG>.
In the 200 properties that the XML has, only 30 have the <PSIG> YES </PSIG> property.

How can i import ONLY those 30 properties and not all 200 properties?

I tried the <<Import only specified records:>> by inserting {PSIG[1]} via drag and drop but it just imports the last property of the XML.

What am i doing wrong?

Thanks in advance

Looking forward hearing from you
