You can read in following document:  Configure Up-stream Traceability Column how to enable up-stream columns. 

We also support the option to have multiple linked work items in the column.

Example: show multiple system element items in Item/Func column

Edit mode:

Configuration:

• we support the same options as for single item column, see documentation

•     {
        "headerGroup":"Potential risks",
        "headerGroupCss":"headPotentialRisks",
        "headerCss":"headPotentialRisks",
        "header": "Item/Func",
        "type": "multiItemLink",
        "width": 150,
        "filterable":true,
        "level": 1,
        "id":"item",
        "canCreate":true,
        "typeProperties":  {
                "linkRole": "assesses",
                "linkTypes": "systemrequirement,softwarerequirement,systemelement"
              }
      },

Restrictions:

• You cannot have sub-columns, e.g. if you have itemLink column showing harm, you cannot have another column showing harm severity via dot-notation (bindings=harm.severity)
