It is still not possible, as already answered here. You may only use an alternative approach described here:
Stop double-clicking the .TXT/.CSV file or opening the text file
conventionally (e.g. CTRL+O) and use the Text Import Wizard to specify
Text format for certain fields within your import file. Start by
opening Excel to a blank workbook and from the Data tab's Get External
Data group, click the From Text button.
After clicking From Text, select your text file from the Import Text
File dialog and click Open. This launches the Text Import Wizard.
There are three pages to complete. The first page is essentially to
determine whether the file is to be considered Delimited or Fixed
Width. The second page depends upon the first. You will be asked what
characters to consider as delimiters or asked to choose the widths of
a fixed width file.
The third page is what is going to help you determine the format of
each field. Select your account id field from the Data preview at the
bottom then select Text from the Column data format list in the upper
left. Note that the header of the field in the bottom Data preview has
changed to Text. Repeat for any other fields and click Finish in the
lower right to complete your operation.
Another way is to use VBA script, like the one here.
