"Upgrade TMs" wizard and custom fields in TMX files

Question

I have a TMX file (coming from WorldServer) containing custom fields that I want to convert into a Studio TM (using Studio 2015 SR2) ideally using the "Upgrade TMs" wizard that comes with Studio. I want the Studio TM to maintain all the 5 fields in my TMX file which are:

<prop type="x-idiom-next-hashcode">
<prop type="x-idiom-prev-hashcode">
<prop type="x-idiom-segment-status">
<prop type="x-idiom-source-ipath">
<prop type="x-idiom-target-ipath">

Which settings allows me to preserve the fields in my Studio TM?

In SDL Trados 2007 Workbench, there used to be an option called "New fields: Add to setup". Does Studio have a similar option?

Or do I need to create an SDLTM from scratch, manually add all required fields and then import my TMX file?

Hi Frank, 
 Don't you have these options when you upgrade?

Hi Paul, thanks a lot for your help:

There seems to be an undocumented feature/bug:

If I change the TMX input file (coming from WorldServer) in this way:

<prop type="x-idiom-next-hashcode:Integer">

<prop type="x-idiom-prev-hashcode:Integer">
<prop type="x-idiom-segment-status:SinglePicklist">
<prop type="x-idiom-source-ipath:SingleString">
<prop type="x-idiom-target-ipath:SingleString">

Then I see all fields as you showed in your screenshot.

Luckily, the API docu contains a list of all values that can be added:
http://producthelp.sdl.com/SDK/TranslationMemoryApi/3.0/html/c2c2edc0-84b1-5d9c-366e-389adb2a80b3.htm

Member	Value	Description
Unknown	0	Field type is unknown.
SingleString	1	The field value contains one string value.
MultipleString	2	The field value contains one or more strings.
DateTime	3	The field value contains one DateTime value.
SinglePicklist	4	The field value contains one picklist value ID.
MultiplePicklist	5	The field value contains one or more picklist value ID's.
Integer	6	The field value contains one integer value.

Nevertheless, I did not find any mention of these "field type values" being required?
