Add custom attribute to Reports

Hi, my devices transmit over Iridium to a decryption server, whereupon the data is sent to the Traccar server (running v5.6 modern UI) using osmand protocol. One of the metrics being sent is Barometric Pressure (using ...&speed=21.2&barometric pressure=1013.3...). When viewing the data on the UI pop-up, by selecting "more details" (by clicking green circle with 3 dots), the attribute "barometric pressure" appears with the expected value (the 'name' column is blank). When I go to Reports, I would like to select "barometric pressure" from the Columns drop-down, but it does not appear there. I would also like to chart barometric pressure under the Charts section. Is there any way to configure a custom attribute so that it appears on these reports?

The only way is to map it to an existing attribute.

Is there an existing attribue list?

Thanks Anton. Let's say I map it to Temperature 4, is there a way to rename Temperature 4 to Barometric Pressure? And is Temperature 4 a float or integer (where can I look at this so I don't have to bother you with it)?

And as a feature request, would you be able to add Pressure 1 to Pressure 4 in a similar way to Temperature 1..4 as standard attributes please? Or even better to a some 'standard' attributes which are customisable.

As a matter of fact everything can be interpreted as "customisable".
