Is your feature request related to a problem? Please describe.

I found the need to convert a field type from a single row to textarea for more information can be added and shown as a text field,

Describe the solution you'd like

Add the conversion of fields to different types if possible, eg

• single text row / textarea
• numeric value / single text row
• options / textarea

Describe alternatives you've considered

If the conversion leads to the complete or partial loss of the values, please, warn users about that.
