Does JSON RegEx assertions support regex shortcuts

If I use JSON Path asseration for $..id and expected resutl is [121,130] the assertion passes. When using the JSON RegEx aseration I set JSON Path Expression to $..id[0] and RegEx to \d and expected result to true the assert fails. But if i set RegEx to [0-9]*, the assertion passes. It appears that REgEx in SoapUI 5.3 for Json RegEx asseration doesnt support regex shortcuts. When will short cuts be supported?
